HARD work and a happy marriage is Doris Field’s secret to a long life.

The grandmother-of-one, who turns 100 tomorrow, is celebrating the occasion with friends and family, including son Oliver Field and his wife Shelagh, and grandson Kevin and his wife Julie.

Mrs Field, of Pensclose, Witney, said: “The secret to my long life is 50 years of happy married life and hard work and a contented mind.”

Doris Lambourne, as she was then, started work at 14, when she became a live-in help at a farm in Kidlington.

She stayed there until she met and married Ellis Field, who died 26 years ago, in 1933.

The couple lived in Fifield, where son Oliver was born, and moved to Idbury in 1935. Mrs Field worked at Idbury house for 40 years, retiring aged 75.

During the Second World War, Mrs Field served in the canteen at Kingham Railway Station, providing refreshments for the troops, and took in three evacuees from London.

She has always been involved in her local church, serving on the Fifield and Idbury Parochial Church Council for more than 50 years, and was also a member of the Women’s Institute and Wychwood Singers.

Other hobbies included crocheting, embroidery and knitting.

Her daughter-in-law Shelagh, of Fifield, said: “She was a very active lady, though now she reads and listens to the radio.”
